"An "object of the invention is -to prov-ide a,

heavy duty, light-weight, highly eflicient unloader'attachment for tripe scaldersyand the like.

Another object or the invention-is to provide an unloader attachment which includes a chute swingable between one or the other'oftwo nor "mal positions, and to means for maintainingthe chute inone or the other of its normal positions and against'accidental or unintentional displacement therefrom.

'A further'o'bject of the invention is to provide an unloader attachmentwl iioh includes a sub= stantially ll-shapd *mounting bracket con struc'ted and arranged to be securely, though releasably, fastened directly to portions-of the charge -discharge port of a tripescalder.

The-numeral l8=denotes a circular charge discharge port provided in the front portion of housing |9,'*said pert controling access'to the interior "of the" housing. "A'suita'ble port closure member 20 is receivable within port l8 during those periods of tim'when the innerba'ske't is to "be rotated, said closure member effectively sealing the contents of the housing therein.

The unloader attachment of'the present invention comprises'a substantially U-shaped mounting bracket'SB inchiding-apair'of laterally spaced side elements 32 interconnectedet their letter I endsas at-34,- wherein the radius of portion 34 and the lateral-spacing-ofside-elements 32 is of a dimension approximating the diameter 'of port I8.- fThe' "mounting bfaket may be' securely, though releasably fastened to the outer race of port It?- by'meafiser suitablef asteriihg'ifi is seen as, by of extreme; bolts 36, whereby tnebraeket'wur b' iir'mly fastened to the device.

In the preferred embodiment the upper seas "of the s'iddelenients ma be turned'90 as at, the up er ends "of each of said elements" extenuifig fo'rwa-rdlyas" aE-4u, dne being pievmea with a u'eshapedslotfik seeflFigg3. v M i As -be st discld'sed' in Fig'yig-a' u 'shaped'niember 44 including span of laterally spaced end rfneriibers 46 connected at one end to a cross member 48* is-providem whereinthe laterally spaced (and members 46 are constructed and arranged wherebytoOVerlappingly engagethe oute'r faces of the upper ends of the laterally spaced side elements 32 of themountirig bracket.

As best disclosed" inFig's. 3 and 4,- a pair of upwardly and forwardly projecting" stop member's -50'are secured to and; carried by cross member 48. In the pref erred" embodiment of the" inventi'on comp'osite-cross member 48 is provi'dedwith rearwardly projecting portions 52 dimensioned to? engage; the inclined wall of the outer housing adjacent"54,--to which it maybe securely, .thoughmeleasably; fastened as by means =-of a bolt,- or'thelike, iii/whereby the'up'per portion of -the unloader attachment will be rigidly mounted relative-tothe housing.

chute "E0 is securedto and carried by the fieeouter ends ci a pair-of laterally spaced-chute'- supporting -'arms "62. A 'ho1low-'sh"aft 6'4 "spans portionser ar'rirs"62 1 remote from the -chute; the ends of said shaft projecting outwardly beyond a arms 62. shaft 64 is welded or otherwise fixed to arms 62 and is of a length so as to fit between portions 48 of side elements 32. A second, smaller shaft 65 extends through hollow shaft 64 and through openings in portions 40 of side elements 32 and end members 46. Nuts 61 or other fastening means secure that shaft to end members 46. The two shafts are dimensioned so as to allow free rotation of shaft 64 about shaft 65.

Those portions of arms 62 beyond the axis of shaft 64 terminate in end arm members 66 which are inclined approximately 45 to the axis of arms 62 between shaft 64 and chute 60, as illustrated in Fig. 3. A counterweight 68 is secured in spanning relationship to the free outer ends of portion of the end arm members 66, as illustrated.

In the preferred embodiment of the invention the free outer ends of stops 50 are notched whereby to receive arms 62 when the chute has been moved to a fully raised, non-operative position as illustrated in Fig. 2 and as indicated in the solid lines of Fig. 3. When the chute has thus been shifted to its fully raised, non-operative position, the counterweight will be located below, and in substantial vertical alignment with, shaft 64, thereby positively though yieldably maintaining the chute in its fully elevated position against accidental or unintentional displacement therefrom.

With reference now to Fig. 1, it will be noted that when the chute has been moved to a fully lowered, operative position, .it will be inserted into port [8 whereby the contents of the rotatable basket within housing l may be expeditiously and automatically discharged via the chute.

In the preferred embodiment of the invention, a pair of laterally projecting interfering members 79 are secured to and carried by those portions of the chute-supporting arms 62 adjacent the chute, said interfering members constructed and arranged whereby to 'abuttingly engage portions of the outer face of the mounting bracket, thereby determining and limiting the amount by which the chute is introduced into the interior 2f the housing when in a lowered, operative posiion.

It will be observed that the counterweight will be swung or shifted to a position above and forward of shaft 64 when the chute has been fully received within housing It for thereby exerting continuous, yet yieldable force operative for maintaining the chute in the position illustrated in Fig. 1.

From the foregoing, it will be noted that I have provided an unloader attachment for a tripe scalder which may be mounted to the outer periphery of the charge-discharge port, said unloader including a chute movable between a fully raised, inoperative position above the housing of the device or to a lowered, operative position located interiorly of the device. It will be further noted that the unloader attachment includes stop means 56 and interfering members 10 for limiting the raised and lowered positions of the unloader, without in any way interfering with the structural or operational characteristics of the tripe scalder with which it has been associated.

As clearly evident from Fig. 2 the unloader is located over or above housing Ill, thereby affording complete access to all portions of the scalder.

It should be understood that various changes 'in'the structural details of the device may be made, within the scope of the appended claims, zvithout departing from the spirit of the invenion.

.for a conventional tripe scalder, which tripe scalder has a casing including a wall formed with a central port bordered by a stiff ring constituting a throat; said unloader comprising a U- shaped bracket formed of a strip of stiff sheet metal and having vertical legs connected at lower ends by an arcuate bridge portion integral therewith, said bracket being of dimensions adapting it to be mounted about the port of the scalder with its bridge portion bearing against the outer surface of the ring for a portion of the circumference thereof and registering with the lower portion of the throat and its legs projecting upwardly above the port at opposite sides thereof, the legs being twisted near their upper ends and terminating in arms projecting forwardly from upper ends of said legs at right angles thereto, a substantially U-shaped yoke having a bridge adapted to be immovably secured horizontally to the outer surface of the wall of the scalder in upwardly spaced relation to the port, the yoke having horizontal arms projecting forwardly from ends of its bridge along outer surfaces of the arms of the bracket and formed with openings registering with openings in the arms of said bracket, a rod extending horizontally between the arms of said bracket and having end portions mounted through the registering open ings, a tubular shaft rotatable about said rod, a chute, an arm extending from each side edge of one end portion of said chute and rigidly secured to said tubular shaft, each chute-carrying arm having a short end portion extending diagonally of the main portion of the said arm from the tubular shaft, a counterweight for said chute extending between and carried by outer ends of the diagonally extending end portions of the chutecarrying arms and disposed in spaced relation to the opposite side of the shaft from the chute, tongues carried by the bridge of said yoke and extending upwardly and forwardly therefrom in position for engagement of edges of their upper ends by the arms of the chute to limit rearward movement of the chute and its arms over the tubular shaft when the chute is swung upwardly and rearwardly to a raised position over the shaft,

- said chute enterin the port and being disposed forwardly at a downward incline when swung forwardly and downwardly and rearwardly to a lowered position for use in which its rear portion passes through the ring, and the counterweight being at the same time swung upwardly between the arms of the yoke and forwardly over the shaft past a dead center and thereby disposed 'forwardly of the tubular shaft in position for urging the chute rearwardly through the port.

2. A preformed unitary unloader attachment for a conventional tripe scalder of the construction defined in claim 1,'wherein the arms of the chute adjacent the chute are provided with laterally extending elements dimensioned to contact the vertical legs of said U-shaped bracket for limiting movement of the chute rearwardly through the port.
